Safety Information
Introduction
Thank you for purchasing this compact, high
performance, air-cooled, engine-driven generator. It is
designed to automatically supply electrical power to
operate critical loads during a utility power failure.
This unit is factory installed in an all-weather, metal
enclosure intended exclusively for outdoor installation.
This generator will operate using either vapor withdrawn
liquid propane (LP) or natural gas (NG).
NOTE: This generator is suitable for supplying typical
residential loads such as induction motors (sump pumps,
refrigerators, air conditioners, furnaces, etc.), electronic
components (computer, monitor, TV, etc.), lighting loads,
and microwaves, when sized properly. This unit is
equipped with a Wi-Fi
generator owner to monitor generator status from
anywhere he or she has Internet access.

away. Failure to do so will result in death
or serious injury.
Protection Systems
The generator may need to run for long periods of time
with no operator present to monitor engine or generator
conditions. The generator is equipped with protection
systems to automatically shut down the unit to protect
against potentially damaging conditions. Some of these
systems include:
Alarms:
• High Temperature
• Low Oil Pressure
• Overcrank
• Overspeed
• Overvoltage
• Undervoltage
• Overload
Warnings:
• Charger Warning
• Charger Missing AC
• Low Battery
• Battery Problem
The control panel contains a display alerting the operator
when a fault condition occurs. The above list is not allinclusive. See Operation for more information about
alarms and control panel operation.
NOTE: A warning indicates a condition on the generator
which should be addressed, but will not shut down the
generator. An alarm shuts down the generator to protect
the system from any damage. In the event of an alarm,
an owner can clear the alarm and restart the generator
prior to contacting an IASD. Contact an IASD if the
intermittent issue occurs again.
